How to open ports on Windows 7: port types and common solutions

Surely many have heard that in some cases it is required to open ports in order, for example, that some resource is available on the Internet. True, not everyone knows how to open ports in Windows 7 - one of the most popular "operating systems" of our time. Let's look at the aspect of the general solutions of this question, and also we will deal with some nuances.

Why do I need ports?

We will not go into the jungle of system processes, but try to figure out how to open ports on Windows 7. First of all, everyone should know that ports, in fact, in the broadest sense, are some universal communication channels through which you can connect to certain resources In the same Internet. This is sometimes a prerequisite for being able to participate in an online game or to access a closed server.

In addition, some specific ports are used by different devices in the system itself. We will dwell on this separately.

How to open ports on Windows 7: a common solution

So, initially this whole procedure is reduced to changing the settings of the firewall. We say at once: this general solution can only be used when the connection is made directly through the cable, rather than a router such as a Wi-Fi router (in which case the ports will need to be configured on the device itself).

How to open ports on Windows 7? As easy as pie. First we go to the Control Panel, where we select the system and security section. After that, select the firewall configuration. In this section, we are interested in additional parameters, after selecting which options will open the settings for advanced security.

In this case, at the top left, we'll use the rules for incoming connections, and then create a new one (the port is selected as the component). In the next step, specify the TCP protocol, the number of the desired port, and then allow the connection. Next, the profile settings that have appeared can be left unchanged. Then enter the name of the new rule and click the "Finish" button.

The issues of opening and changing com-ports

As for how the com-ports of Windows 7 are opened, there is nothing particularly complicated here either. Sometimes such a procedure is needed to reassign reserved ports for some devices or simply delete unused ones.

First click on the computer icon on the desktop and select the property bar. On the tab, we also click on the variable environment button , and then we need to create a new variable called DEVMGR_SHOW_NONPRESENT_DEVICES with a value of 1 (this will show all the ports and devices using them in the corresponding manager).

Now we call the Device Manager either from the Control Panel or by the devmgmt.msc command, enter the "Run" menu bar. In it, you need to sort the list of devices by type. In the section COM- and LPT-ports all unused devices will be visible, which unnecessarily occupy corresponding ports. You can completely remove them. Port reassignment is performed in the submenu of the properties of any component installed in the system.

How to open ports on Windows 7 for Minecraft

As for opening ports for one of the most popular online games called Minecraft, you can use two main methods here: set them up manually or use special utilities, which is much easier. Let's start with the second one.

You can install a small utility called Simple Port Forwarding, after launching the program, you must specify the port number 25565, your IP address and expose some additional parameters. But here it should be noted that the application is shareware, and a week after the start of use it will have to buy.

So, the user will need to know how to open ports on Windows 7 for this game manually. Let's analyze the situation with the example of routers. To start with the browser, you need to enter its settings and refer to the Port Forwarding section. Here it is necessary to create a new connection, and in the configuration sheet enter the IP of the router itself, the ISP of the ISP server, the number of the desired port (25565), and do not forget to check the TCP protocol. After that, you need to save the settings and just restart the router and computer (laptop). As you can see, this technique is somewhat more complicated, as it will be necessary to contact the provider (at least, in order to find out the address of its server).

Conclusion

If we sum up a small result, we can say that there is nothing particularly complicated in opening the ports in the G-7, however, as in any other system. Here you just need to pay attention to the type of port being opened, since this will determine the specificity of the procedure that is being performed. Needless to say, it is necessary to take into account the type of Internet connection, because the general method works only in cases of direct connection of a computer or a laptop via fiber optic cable. For a Wi-Fi connection, the configuration of the router is similar to connecting to Minecraft servers. In extreme cases, all the necessary data can be obtained from the provider, if automatic configuration of certain parameters is not provided. Finally, nothing can happen if some ports are simply not supported by the provider or are blocked for some reason.
